I want to ask something. I have done three small projects on Java at Netbeans. Can I make a project which it calls theese three projects ? I want to have all theese projects in one programm. Thank you !
Basically, yes.
Expand the "master" project and right click on the "Libraries" node.
From the popup, select "Add Project". Browse to the location of the project you want to link and select "Add Project JAR Files".
The project will now be linked to your project and you should be able to access it's classes.
Note, if the child project has any dependencies of it's own, you will need to add those to the "master" project as well.
You can either add those projects into your new program build path or make the libraries and use it.

I have already a project in Eclipse, a old project. So everything is already set up, but i don't know how can i add a folder named third_party, which contains some specific jars.
My goal is not to change the librairies of a project, but just to add one thing to fix all my dependency's problems.
Best Regards
I think you can't; you have to add JARs manually - but normally the "Add jars" dialog should allow you to select multiple JARs in one shot.
But what you can do is: define a project, that only contains your JAR files in the build path; and export all of them. Then you can make this project (maybe called "libraries" a pre-req for your other projects).
In other words: have one project that "collects" and exports all JARs that you need; then use that project in your other projects.
You could create a new User Library and add it to your project. that should take care of your dependency problem. You are not changing any libraries, but just adding the ones you need for the updates to the dependency issues.
currently, I'm trying to use a pac-man simulator that I found in the github in this link.
The project is consist of two main folder. Pacman-vs-Ghosts and Pacman-vs-Ghosts-Agents. I was able to run the codes inside Pacman-vs-Ghosts folder by using 'import existing project' option in the eclipse.
However, I could not figure out how could I run the second folder Pacman-vs-Ghosts-Agents. On the repository readme, it is written that
PacMan-vs-Ghosts-Agents -> example agents (both Ms PacMan and Ghosts), this project must reference PacMan-vs-Ghosts in order to compile
However, this is my first time with Eclipse so I could not find how to reference to Pacman-vs-Ghosts from the PacMan-vs-Ghosts-Agents project.
If possible could you explain me point by point (couple of picture would be great) how to do that?
You have many means .
1 If you have the source code and know what you want to reuse, just extract some java files, and put them in your project
2 If you have many dependancies, or if you want simply solution, get it or package it as as Jar , and include it in your project
You need to import both projects into the same workspace. Then you right click on the dependent project (PacMan-vs-Ghosts-Agents), Build Path > Configure Build Path, go to the projects tab, click Add and select the dependency (Pacman-vs-Ghosts).
I am new to Java and have been learn as I go.
I am having a problem where I have developed a library of objects in one project and I now want to use them in two other projects. I started doing this by copying the packages from the first project into the second and third projects, however I would now like to make changes to the library and I would like these to be reflected in the second and third project, which obviously they are not.
Project1
-package1
-package2
-package3
Project2
-packageA
-packageB
-package1
-package2
-package3
Project3
-packageC
-packageD
-package1
-package2
-package3
I would like for the packages to be in the second and third project to be updated automatically when I update them in the first project, although I also don't mind doing the refresh manually. At the moment it is just me working on all off the projects but it could be the case in the future where more people are working on them, therefore I don't mind suggestion which would have this move onto some collaborative platform (I'm aware of SVN but have never set one up)
In eclipse you can do this as follows.
Import your project to your workspace.
Mark it as library project
Right click your project you want to make as library and select Properties. Select Android on the left and tick the checkbox IsLibrary. Done.
Reference the marked project
Right click your project in which you want to add the library project and select Properties. Select Android on the left and Add... your marked project. It will be added to the list and is ready to use. Now you are able to access all classes and ressources (e.g. drawables, strings) from the referenced, marked project. Awesome, eh? :)
I have multiple project source which I checkout from SVN and put in project one
I want project two to point to specific part from these sources and
project three to another part of the sources from this multiple project.
How can I do that in eclipse ?
So when I make a change in project two, when say SVN synchronize on project one to see that the sources have been changed.
PS. I use gradle and for me it is much easier to build only one subproject, not the whole tree every time and ofcourse to see Eclipse Ctrl+space helps.
Right click on project two, and left click on Properties.
Left click on Java Build Path. Left click on Add Class Folder.
Check the class folder (bin) from project one. Left click on OK.
Back on the Java Build Path dialog, left click on OK.
Go to your second project's properties, to Java Build Path, then to the Source tab, and click on Link Source... button. There, click on Browse... button and select the src folder of your first project. This will allow you to change the source files from either project, and compile them from either project as well.
I have several modules of a project and i have made each module as a project in eclipse as a seperate project..
Now i want to combine those projects in a masterproject..
Is it possible to do it?
thanking you in advance!!
Right Click on project. Go to build path->Configure build path->Projects. here you can add any project (which is already in eclipse) on the build path.
Yes. You can easily set things up so that one project uses other projects. Simply right click on the project in the package explorer, then click Build Path, then Configure Build Path, then add Project. Voilà!
